Business to Business Connections
The following
Business to Business
connection call flow options are supported:
FW (Firewall) NAT Keep Alive
The Collaboration Server can be configured to send a
FW NAT keep alive
message at specific
Intervals
for the
RTP,
UDP
and
BFCP
channels.
This is necessary because port mappings in the firewall are kept open only if there is network traffic in both
directions. The firewall will only allow
UDP
packets into the network through ports that have been used to
send packets out.
By default the Collaboration Server sends a
FW NAT Keep Alive
message every
30
seconds. As there is
no traffic on the
Content
and
FECC
channels as a call begins, the firewall will not allow any incoming
packets from the
Content
and
FECC
channels in until the Collaboration Server sends out the first of the
FW
NAT Keep Alive
messages 30 seconds after the call starts.
